This invention relates to an automobile truck provided with mechanismfor receiving a load and moving it through two stages of operation intotransportable position, and after transportation, depositing it.

The general object of the invention is to provide simple and eflicientpower macha nism for raising and positioning the load and effectivelycarrying it during transportation and readily depositing it under theaccurate control of the operator.

A further object of my invention is to provide mechanism for controllingrelative movement of the load engaging member and a boom or frame uponwhich such member is pivotally mounted and in which the load engagingmember is movable about either of two axes substantially normal to eachother.

More particularly my invention provides a truck equipped with a flexiblemember extending over a suitable boom hinged at its lower end to thetruck frame, the load being received in a suitable support pivoted tothe lower end of the boom. The flexible member first raises the load bytipping the boom over the truck body and then up-ends the load byrotation of the pivotal support into a convenient transportableposition. A suitable spring mechanism supports the tipped boom andautomatically returns it toward loaddischarging position, when therelaxing of the flexible member permits such movement.

My invention may be embodied in a truck adapted for receiving, elevatingand up-ending pa er rolls, and transporting them and therea terdepositing them.

The above features and others contributing to the efiiciency of themachine are hereinafter more fully explained in connection with anapproved embodiment as shown in the accompanying drawings. The essentialcharacteristics of my invention are summarized in the claims.

In the drawings, Fig. 1 is a side elevation of the truck with the artsin position just after receiving the load in this case a paper rolllying horizontally; Fig. 2 is a similar view showing the parts inposition with the boom tipped and t e load still horizontal in extremeelevated position; Fig. 3 is a similar porting the load, the load havingcharged; Fig. 5 1s a rear elevation of the truck and load in theposition described in Fig. 1; Fig. 6 is an enlarged view in sideelevation, parts being shown in section, showing in detail the hingedconnection of the boom with the rear end of the truck, and the pivotalarrangement of the load-receiving member at the lower end of the boom;Fig. 7 is a front elevation of the casting constituting the lower end ofthe boom for receiving the pivotal paper roll support; Fig. 8 is a planof the same; Fig. 9 is a front elevation of the pivotal paper'rollsupport; Fig. 10 is a detail in horizontal section, illustrating thewinding mechanism which may be emplo ed; Fig. 11 is an enlarged verticalsection 0 the same taken on the line 1111of Fig. 10, and Fig. 12'is atransverse section of the same on the line 1212 of Fig. 11.

As shown in Figs. 1 to 4, 10 indicates th frame body of the truck whichis supported by rear wheels 11 and forward wheels 12. These forwardwheels are on opposite sides of a front housing 13 composed of uprightand transverse members secured to the frame member 10. This housing maycarry a suitable motor (not shown) for rotating the front'wheels, andthese wheels may besteered by any mechanism, not shown. On the upperpart of the front housing is a space 15 suitable for a storage batteryfor driving the truck, and this same battery may be availed of foroperating the cable-winding mechanism hereinafter described.

The construction of the frame, wheels, housing, etc., above mentioned,does not enter into the present invention. They may if .desired beformed according to Patent No. 1,260,145, granted March 19, 1918, to theElwell-Parker Electric Company as assignee of Clyde E. Cochran.

In the present invention, I hinge to the rear end of the truck frame 10a boom 20. This is composed of an approximately upright member, shown asan outwardl facin channel beam bent into inverted \Zshape form andsuitably braced as at 23. Between the arms of the channel beam andrigidly secured to them at their lower ends is a casting 21 whichisivoted at 22 on a horizontal pivot to the true frame.-

The casting 21 is provided with bearings ada ted to receive in pivotalrelation the stub shaft or axle of asecondcasting to which is suitablysecured a scoop 50, the casting '45 and scoop together constituting asupany desired manner.

The load supporting member preferably consists of the casting 45illustrated in Figs. 6 and 9, to which is suitably secured as by boltsor rivets passing through holes 27, the arcuate scoop 50 having apartially closed end 56 and projecting ugs 57 mounted on suitable plateswhich are secured to the scoop 50. Located between the plates 55 arereinforcin ribs 58 between which an armate retaining latch 49 issuitably mounted. Projecting forwardly from the center of the casting 45is a tapered hollow stub shaft or axle 31 having inserted at the forwardend a hardened steel ivot 32 havinga reduced threaded end a apted toreceive a nut 33.

The stub shaft 31 is adapted to rotate in ball races 34 within the rearportion of the casting 21, while the forwardly extending pivot. 32 has abearing within ball races 35. A protecting cap 36 may be secured as bybolts 37 to the outer end of the hub 16.

Dep ding from the top portion 24 of the boom at the junction of the armsof the in-' vertcd U-shaped member is a pulley block 25 over whichextends a cable 30. One end of this cable passes to a suitable windingdrum as illustrated at 113 in Figs. 1 to 4. The other end of the cablemay be suitably attached to either of the ln s 57 on thescoop 50.

By properly locating t e lugs 57 with relation to the centre of gravityof the load the moments acting on the scoop 50,'due to the drawing in ofthe cable 30 when attached to the lu 57, can be so determined that therotation 0 the winding drum at 113 will first tip the boom forward yover the rear portion of the truck, as shown in Fig. 2, with the loadremaining in the horizontal position and upon a further drawing in ofthe cable 30 the scoop and load will be rotated in the bearings 34 and35 until the load will be up-ended into a substantially upright positionas shown in Fig. 3, the ear 152 and lug 151 acting as a position stop.

The pivotally supported casting is provided with a shoulder 59 which isin the posi tion as illustrated in Fig. 9, when the scoo is horizontalas in Figs. 1 and 2. The shou der 59 is adapted to engage and operateautomatic mechanism for controlling the cable which will be hereinaftermore fully described.

Toward the outer end of the scoop a load retaining latch 49 is slidablymounted between the arcuate ribs 58 and engages a substantial portion ofthe circumference of the roll when drawn out to the roll lockingposition.

On each side of the boom I provide a suitable resilient connection witha portion of the truck frame in front of the pivot 22. As illustrated, Ipreferably pivot to each arm of the channel beam constituting the boom,the upper end of the tubular sockets 60. Extending from these socketmembers, coaxially therewith, are rods 62. These rods extend looselythrou h tubular heads on partially tubular mem ers 64, pivoted at 65 tothe frame 10. On the lower ends of the rods 62 are nuts 66 limiting theupward movement of the rods. Surrounding the reduced u per ends of therods and bearing against co lars formed at the junction of the reducedand full sized portions of the rods and extendin into the bore of themembers 60 and seate against the far end of such bore, are compressionsprings 67. p

The construction described provides two lateral tie members for the boomadapted to limit its outward swing to substantially vertical position,as shown in Figs. 1 and 4. These springs provide an elastic cushion forthe boom when it is drawn forwardly by the cable over the truck frame,the rods 62 telescopingwithin the tubular members 60 and 64, allowingthe socket member 60 to approach the tubular member 64 as illustrated inFigs. 2 and 3. The engagement of the mbmbers 60 and 64 forms a positivestep limiting the inward swing of the boom. When the cable is releasedthe reaction of the springs and the weight of the load raises the boomto the upright position of Fig. 4, suitable for dischargin g the load.

Fig. 1 indicates at A a paper roll lying horizontally in the scoop 50.The lugs 57 are located on the scoop 50 as hereinbefore stated in such amanner that a tilting movement of the load will take place before theload rotates on the pivot 45. I have found that such an arrangementrequires one or more terminals or lugs for the cable 30 and the end ofthe cable is attached to the upper or lower lug 57 in accordance withthe length of the paper roll being handled.

When the roll has reached the up-ended position shown in Fig. 3 theshoulder 59 will have rotated sufliciently to engage a bell crank lever68 and automatically open a switch controlling the winding drum. Theload is now in position for transportation by the truck as desired.

It will be seen that with the mechanism described, the truck may bebacked into position adjacent to a. horizontal paper roll and the latterrolled into the scoop. The end of the cable may then be attached to thescoop and the winding motor started. The boom will immediately be tippedover the truck' frame and yieldabl sup orted, thereby raising the load,and t erea ter tilting the same into substantially upright positionresting on the end 56 of the scoop, ready for transportation. When thedesired new location is reached the paper roll is deposited simply bypaying out the cable 30. The first result of this paying-out movement isfor the springs 67 to raise the boom sufliciently for the weight of theload to complete the movement into upright position as shown in Fig. 4,whereupon the edge of the paper roll, away from the end of the truck,will drop by gravity to the floor and the truck may be moved forwardlywithdrawin the end 56 of the scoop 50 from the roll an leaving itdeposited in upright position.

Any suitable winding mechanism may be provided for pulling in and payingout the cable 30. I find it very convenient to use an electric winch forthis purpose, which provides a winding drum, a motor geared to it andsuitable mechanism making thedevice self-locking whenever the motorrotation stops, but enabling the winding in at will and also the payingout of the cable whenever desired, by rotating the drum in the unwindingdirection faster than ravity and the action of the springs 67 ten torotate it.

A convenient form of winding mechanism as above outlined is illustratedin Figs. 10,

11 and 12, where the winding drum 100 is on a shaft 101 which carries aspur gear 102 meshing with a pinion 103 on a shaft 104. A spur gear 105on this shaft meshes with a pinion 106, on a sleeve 107 which is looseon the shaft 101. Surrounding the sleeve 107 is a spur gear 108 which isconnected with the sleeve by means allowing independent movement foronly a fraction of a rotation. This gear 108 meshes with a pinion 109(Fi s. 1 to 4) on an extension of the armature s aft of a motor 110.Between the gear 108 and the pinion 106 is a friction brake effectivewhenever the raising rotation stops. This consists, as shown, of a disc111 rigid with the sleeves 107, an annular friction member 112 alongsideof the disc and held stationary b engagement with the casting 113 of thewin -ing mechanism, and an annular cam member 114 on the other side ofthe friction member 112 and loosely splined on the sleeve and having onits outer side a face cam 115. This cam is adapted to be abutted by acomplementary cam 116 which is rigid on the sleeve 107 and has a portionextending within the spur 117, fig. 12, which are occupied by lugs 118on the cam member 116 to allow some freedom of movement between the arand cam member. After this freedom is taken up in the raising rotationof the gear, the gear drives the cam member 116, and this, by reason ofthe direction of the inclines, frees the brake member 114 from brakingfriction and positively carries it around by reason of the engagement ofthe shoulders on the two cams.

It will be seen, therefore, that in the raising direction the mechanismprovides first for relieving the brake, and then for furnishing a directtrain of spur gearing between the armature and the raising drum. Whenthe raising rotation ceases the tendency of the load is to rotate thetrain of gears in the opposite direction, and as the gear 108 moves inthis backward direction the brake member 114 lags behind it so that thebrake becomes applied by reason of the inclined action of the cams andthe load is held.

To lower the load the armature is simply driven in the reverse directionfrom the raising movement. This turns the gear 108 backwardly fasterthan the load would turn it, and in this movement webs 119 on this gearengage lugs 120 on the cam member 114, and carry it around so that thebrake is not applied.

The engagement of the webs 119 with the lugs 120 takes place before theother ends of the notches 117 engage the lugs 118. VVhenever thislowering rotation of the armature stops, the tendency of the load topull the ear 108. The gear 108 has notches train of gearing applies thebrake, as already 1 described.

- It will be realized from the above dmription that the deviceillustrated is self-lock- 111E whenever the motor rotation ceases, wether it has been raising or lowering the load. It is to be understood,however, that the winding mechanism so illustrated and described issimply set out by way of illustration, as any self-locking windingmechanism may be used. The particular winding mechanism shown isbelieved to be manufactured under Patent No. 1,020,014, granted March12,4912, to G. A. Armington, to which reference may be made for a fullerdescription of it.

The winding motor is shown as suptip ing the latter.

is one of the uses of the present truck is v for handling paper rolls,it is desirable to rovide automatic mechanism to stop the inward swingof the boom at a definite point, thereupon tilt the roll into asubstantially u right position andthen stop the operation 0? the wlndingdrum. It is desirable-also to have the mechanism under the constantcontrol of the operator for lowering the roll so 7 that it may be gentlydeposited in an upright position from the truck. I provide a simplemechanism for efiecting these results, which is shown in Figs. 1 to 4and which will now be described. y

130 indicates a suitable doubleole double-throw knife switch adapted toreak the current in either direction onthe raising motor 110, the bottomposition of the switch being for raising andthe top position forlowering. This switch is operated by a push between the collar 137 andthe two brackets 136, are compression springs 138 so that the handlecanbe moved in either direction only against the springs, whichtend torestore the handle to neutral position.

The knife switch is swung into raising position by an outward pull onthe handle 145 which causes a downward pull on the link 131 through thebell crank described. Rigidly connected with the bell crank is a thirdarm 139 having secured thereto a collar 140 slidably receiving a rod 141having ad'ustably fixed collars 142and 143 thereon. To startthe raisinoperation the operator simply pulls out the andle- 145. The motor now 0rates and winds up the cable 30, tipping t e boom forwardly over therear portion of the truck and at the same time raising the a r roll. Asthe boom is coming into its 6215 horizontal position as shown in F1 2 asthe drum 113 continues to draw the cab e in the scoo containing thepaper roll is then revolved a at the pivot bearings 34 and 35 and (pullrod 135, which carries an operating until a is tilted into up-endedposition. As the boom approaches its extreme forward tipped osition therod 141 slides idly through the col ar 140 until the fixed collar 143there'- on approximately reaches the collar 140.

As the paper roll ap roaches its up-standing position the shoul er 59strikes the up'- standing arm on the bell crank 68 projectin thru anopening 27 in the casting 21, an moves the arm 68 downwardly from theposition shown in Fig. 3.. This movement is transmitted through the rod141 the collar 143 engaging and moving the collar 140 sethe load beinlowered as long as the handle 1 is held in. henever the operatorrelieves the force on the handle thesprings 138 restore the handle toneutral position, which swings the switch open and stops the motor, imdlthe self-locking mechanism holds the When the load has been lowered tothe osition shown in Fig. 4, the paper roll wil tip under the influenceof gravity until the ed e remote from the truck strikes the floor. Thetruck may then be movedforwardly, which will withdraw the scoop from theroll'and leave it diposited in up-ended position. As shown in ig. 1, thelower side of the scoop, when in horizontal position, is heavier thanthe up er so that after do ositing the load, after t e Fig. 4 positionas been reached, gravity will cause the empty scoop to return tohorizontal position, As it comes into such position the In 150 (Fig. 9)will strike the under side of t e bell crank arm 68 andraise the samefrom the Fig. 4 position to that shown in Fig. 1, thereby restoring theswitch 130 to neutral position. 1

By the above described means the load-sup porting member may be raisedand tilted and thenlowered under constant control of the operator, andyet be automatically stopped upon reachin extreme movement in eitherdirection, there y preventing any possible damage from failure of theoperator to stop the motor by movement of the handle 145.

The truck may be also utilized in lifting a roll that is in an up-endedor vertical 1- tion. The ear 56 on the lower end 0 the scoop is beveledalong the outer edge to prevent damagin of the roll when the truck ap-'proaches it w 'le in a vertical position, and the counterweight 153 actsto tilt the scoop to a horizontal position.
